The number of positioning holes 8 is the same as that of the filler post 11, and their positions correspond to those of the filler post 11 to ensure that the filler post 11 can accurately enter the battery steel shell. Next, hydraulic cylinder 4 is activated. The piston rod of hydraulic cylinder 4 extends, causing the lifting plate 5 to descend, and the connecting plate 10 descends accordingly. The filling column 11 is gradually pressed into the battery steel shell, completing the filling operation. The piston rod of hydraulic cylinder 4 retracts, the lifting plate 5 rises, and the connecting plate 10 and the filling column 11 return to their initial positions. Finally, after the operation is completed, check whether all parts of the equipment are normal, clean the residual material in the positioning hole 8, and ensure the performance of the equipment for the next use.
